If you are looking to store and retrieve remote connections, Terminal app on the Mac already has this in-built. Open Terminal - Go to Shell -New Remote Connection.
WinSCP (Windows Secure Copy) is an open-source file-transfer application that leverages Secure Copy Protocol, File Transfer Protocol, and Secure Shell File Transfer Protocol. It primarily serves as a secure file transfer program between a local and remote machine. WinSCP is only a Windows-only program and does not support another operating system like macOS.
It supports several features that come with the Windows OS such as dragging and dropping files. The applications are written in C++, and its first release was in 2000. It is one of the best SSH File Transfer Protocol (SFTP) and File Transfer Protocol (FTP), and Secure copy (SCP) client for Microsoft Windows.
Moreover, the application’s primary function is that it provides a file manager and file synchronization. Apart from working as a file transfer application, programmers can also use WinSCP as a remote editor. When a user launches a file on a remote file manager, it will copy it to the local computer and open in the editor. More so, upon saving the document, the remote file is automatically updated.
Download WinSCP
WinSCP leverages cryptography in SSH to secure login information. The primary benefit of the program is that it protects the connection against malicious attacks such as password sniffing.
Users can download the free award-winning application from the official website. Below are steps to install WinSCP on windows operating system.
Uninstalling WinSCP
In case one wants to uninstall WinSCP, the user has to open the Control Panel. Once done follow the path – Programs > Uninstall a program.
For Windows 10, navigate to following path Settings > System > App and Features. Uninstall the WinSCP the program.
Use WinSCP
Upon installation of WinSCP, a login window will open automatically. In the resultant window, the user has to add various information of the port they want to connect to such as file protocol, port number, hostname, etc.
It will prompt a form that users have to fill in the following manner.
Integrating PuTTY to WinSCP
A PuTTY is a great tool when one wants to connect to Linux shell command line. Users can also choose PuTTY’s alternative Kitty also offers same and more functions than PuTTY. Once the user has WinSCP installed and connected to Linux server via SSH, they can follow below steps to integrate PuTTY into WinSCP.
1. First and foremost, download PuTTY from here.
2. Put the files in the following location to avoid modifying the command line
- %PROGRAMFILES(X86)%WinSCPPuTTY
3. Without logging into WinSCP, click and Tools > Preferences.
4. Next, click on the option ‘Integration and then ‘Applications in the left column.’
5. Now, open the PuTTY/Terminal client path and add the following command
- %PROGRAMFILES(X86)%WinSCPPuTTYputty.exe -t -m '%TEMP%putty.txt' !`cmd.exe /c echo cd '!/' ; /bin/bash -login > '%TEMP%putty.txt'
6. Next, choose the option ‘Remember session password and pass it to the PuTTY option.’ This option will save time for users as they won’t need to reenter the password again.
7. Click on ‘OK’ and Voila! It’s done.
While one can integrate PuTTY to WinSCP, users can also WinSCP as PuTTY session manager; in fact, it has added advantages. Users can use WinSCP to open the site in PuTTY from its Login dialog easily.
From the WinSCP window, navigate to the following path Use Manage > Open in PuTTY command.

PuTTYgen With WinSCP
PuTTYgen is a component of the world’s most sought-out SSH client PuTTY. It comes as part of the WinSCP installation package, and users can even choose to download from here.
In simple words, PuTTYgen is a crucial generator tool that generates both private and public keys. It supports several network protocols such as SFTP, Serial, SSH, SCP, Telnet, etc.
To use PuTTYgen, go to ‘Tools’ in WinSCP and then select PuTTYgen on login dialog.
WinSCP Alternative for macOS
WinSCP for mac is not available. However, there are several alternatives that users can choose that similar offer functions as WinSCP.
The most south-out alternatives include FileZilla, Transmit, Cyberduck and Forklift.
FileZilla -best WinSCP alternatives for macOS
FileZilla is one of the best WinSCP alternatives for macOS and a robust FTP-client. The application packs a number of features and is compatible with Mac and Windows operating system. The open-source application also supports proxy connections, Kerberos GSS security, and firewalls.
ForkLift – Mac-only WinSCP alternative
A ForkLift is a Mac-only application. It is one of the best file managers for the Mac that connects to SFTP servers, and even manage mobile devices on Bluetooth. More so, the dual-pane offers users more flexibility and increases productivity.
Cyberduck – an open source WinSCP for mac
Cyberduck is another open-source WinSCP alternative for Mac that also is compatible with Windows. The user-friendly software interface makes it very easy to use the program. Among its main features is the bookmark manager.
Transmit – FTP app for mac
Transmit is commercial Mac-only software that is one of the best file transfer applications. The robust program makes it very easy to manage multiple files. The app has added advantages that it connects to cloud services that many of its competitors don’t connect, while also maintaining the standard FTP and SFTP. Among the popular cloud services that it connects include Microsoft Azure, Dropbox and Google Drive.
Features of WinSCP
WinSCP is the most south-out file transfer application for Windows operating system. Its website claims that it is downloaded more than 121 million times. The software is packed with numerous features, hence, making it the most preferred application to transfer files between host and remote computers.
Among its top features include – a friendly graphical user interface, Scripting and task automation, integrated text editor and support for multiple languages. More so, it allows users to choose from various user interfaces. It has other features such as file encryption, master password, transfer resuming and the transfer queue.
Downside of WinSCP
WinSCP is one of the most popular SFTP client, but it does not have inbuilt support for terminal emulation. However, programmers can use it with a famed free serial console and terminal emulator – PuTTY. Its other disadvantages are that it does not allows keyboard shortcut mapping. It also does not support toggle between two interfaces.
The above is a brief on one of the most used Windows file transfer application. One can use WinSCP or choose any of its alternatives for secure file transfer.
This page is about PuTTYgen on Linux. For the Windows version, see the PuTTYgen on Windows page.
Puttygen is the SSH key generation tool for the linux version of PuTTY. It works similarly to the ssh-keygen tool in OpenSSH.
The basic function is to create public and private key pairs. PuTTY stores keys in its own format in
.ppk files. However, the tool can also convert key formats.
Installation
In some Linux distributions, the
puttygen tool needs to be installed separately from the Putty client. For example, in Debian Linux, the following command will install it:
Creating a New Key Pair for Authentication
To create a new key pair for authentication from the command line, use something like:
It is strongly recommended that a passphrase be used for key files intended for interactive use. Key files used for automation (e.g., with WinSCP should generally have an empty passphrase.
Installing the Public Key as an Authorized Key on a Server
With both Tectia SSH and OpenSSH servers, access to an account is configured by generating a public key, copying the public key to the server, and adding the public key to a ~/.ssh/authorized_keys file.
To extract the public key, use:
Then log into the server, edit the
authorized_keys file with your favorite editor, and cut-and-paste the public key output by the above command to the authorized_keys file. Save the file. Configure PuTTY to use your private key file (here keyfile.ppk ). Then test if login works. See configuring public key authentication for PuTTY.
Changing the Passphase of a Key
It is recommended that all SSH keys be regenerated and changed periodically. The Universal SSH Key Manager can automate this. Just changing the passphrase is no substitute, but it is better than nothing. These instructions can also be used to add a passphrase to a key that was created without one.
Use the following command to change the passphrase:
This will prompt for the new passphrase, and write the result back to
keyfile.ppk with the new passphrase.
Exporting a Private Key to Tectia SSH or OpenSSH
It is rarely necessary to export a private key from PuTTY to Tectia SSH or OpenSSH. However, the process is described here, as it can sometimes be necessary when, for example, an application is moved to Linux in the cloud and the destination server of a file transfer cannot easily be reconfigured to change an authorized key.
Tectia SSH and OpenSSH both support the OpenSSH private key file format, so using that key file format is described here. Tectia SSH also supports certain other formats.
To convert an existing PuTTY private key for Tectia or OpenSSH, use the command:
Then copy
keyfile to the .ssh directory on the host where Tectia or OpenSSH will be run.
Command Line Options
The basic command line of PuTTYgen:
The basic command line is:
The options are:
keyfile Name of existing key file to read, when modifying an existing key.
-t keytype Specifies to the type of a new key to generate. Acceptable values include
rsa and dsa . rsa1 is also supported to generate legacy SSH-1 keys, but they should never be needed any more.
-b bits Specifies the number of bits in the key. For DSA keys, 1024 is a decent size. For RSA keys, 2048 or even 4096 bits are recommended.
-q Suppresses messages about progress during key generation.
-C new-comment Specifies comment to describe the key. The comment does not impact the operation of the key. The comment can be specified for new keys or for existing keys to change their comment. Typically the comment would be used to identify the key owner, but since any value can be specified, it cannot really be relied upon.
-P Requests to change the key's passphrase. The tool will prompt for a new passphrase. It is not possible to specify a passphrase on the command line. The passphrase will be used to encrypt the private key. See more details on passphrases and how to generate good ones.
--old-passphrase-file file Specifies a file from which to read the old passphrase of the key. This is only needed if manipulating an existing key that is protected by a passphrase.
--new-passphrase file Specifies new passphrase for the key. This can be used when creating a new key, or with the -P option to change the passphrase.
-O output-type Specifies what to output. By default, the private key is output. The following values can be specified:
-l Same as -O fingerprint.
-L Same as -O public-openssh.
-p Same as -O public.
-o output-file Specifies the output file. This option is mandatory when generating a new key. Otherwise, when changing the passphrase or comment, the default is to overwrite the original file. When outputting a public key or fingerprint, the default is standard output.
-h or --help Outputs help text and usage summary.
Download Puttygen For Mac
-V or --version Outputs version number of the tool.
Putty And Puttygen For Mac
--pgpfp Outputs the fingerprints of the PGP Master keys used for signing new versions of PuTTY.
